Steam-engine regulator

HENRY VEBSTER, OF BEETOWN, WISCONSIN.

STEAM-ENGINE REGULATOR.

Specicaton of Letters Patent No. 13,019, dated June 5, 1855.

To all whom t may concern Be it known that I, HENRY lVnBsTER, ofBeetown, in the county of Grant and State of l/Visconsin, have inventeda new Governor' for Marine and other Steam-Engines; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming partof this specification, in which- Figure 1, is a vertical section of thegovernor and F ig. 2, a vertical section of part of the same at rightangles to Fig. 1.

Similar letters of reference indicate corresponding parts in bothfigures.

This governor consists of a ioat placed within a vessel which is keptconstantly supplied with water by a small pump or pumps driven by theengine, and which is provided with a suitable aperture from which thereis a const-ant escape which is regulated by a valve. The iioat isconnected with a throttle valve or cut ofl'. Vhen the engine continuesto run at the desired velocity the water escapes from the vesselas fastas it is pumped in, but if the speed of the engine increases, the water,is pumped in faster than it can escape and the float rises and by itsaction on the throttle or cut off causes the supply of steam to bediminished or if necessary stopped altogether, and if the speed of theengine diminishes the level of the water in the vessel falls and with itthe ioat thus acting on the throttle or cut off to increase the supplyof steam.

To enable those skilled in the art to make and use my invention I willproceed to'describe its construction and operation.

A, A, are two double acting force pumps whose pistons are driven by twocranks a, a, set at right angles to each other on the shaft B, so as tokeep as nearly as possible a continuous flow of water into the vessel C.The shaft B, is to be driven by a belt or gearing from the main shaft oft-he engine so that the velocity of the pumps always corresponds withthat of the engine.

D, is a float resting on the column of water in the vessel C, and cl, isa rod attached to the float and working through a guide to connect withthe throttle valve or cut olf.

e, is the escape opening of the vessel C, fitted with a Hap valve f.

E, Fig. 2, is a rod suspended'loosely from an arm g, which is secured tothe rod d. This rod has attached to its lower part by a hinge joint z',a variable inclined piece y', which regulates the opening of the valvef, This variable inclined piece is adjusted at a suitable inclination bya set screw Z, in the rod D, and the rod D, is adjustable toward .orfrom the valve by a screw m, which works in a fixed guide piece n.

The valve f, hangs quite free but when the governor is in operation willbe forced by the escaping water into contact with the inclined piece j.The' rod E, with the inclined piece are so adjusted by the screw m, thatwhen the engine works at the desired speed the valve f, will open justwide enough` for the escape of the water pumped up to the vessel C, bythe pumps and allow the float to remain stationary but when the velocityof the engine increases the water being pumped up faster will rise inthe vessel and cause the Hoat D, to rise and carry up Y the rod E, whoseinclined piece y', in rising will gradually close the valve thuschecking the escape of water and causing the iioat to rise still fasterso that its action on the throttle valve or cut off will be very quick,and if the velocity of the engine is not almost immediately reduced thesteam will be shut off altogether. Vhen the velocity ol' the engine isdiminished, the level of the water in the vessel C, begins to descendand with it the float D, which brings down the rod E, and allows thevalve f, to open. wider, thus facilitating the escape of water andcausing the float to descend still faster to give a greater supply ofsteam. The quickness with which the valve opens and closes as the Hoatrises depends on the inclination of the variable piece j.

This governor is very sensitive and quick in its action and would bewell adapted for marine engines. Owing to the small size required forthe pumps the escape water will be so small as to be productive of noinconvenience and to be easily carried away.

Instead of the flap valve f, a slide valve may be employed, connectedwith the float in such a Way as to Contract the opening' as flap Valvef, and the rod E, With its inclined the float rises and enlarge it as itfalls. This piece y', all applied and operating substan- 10 flott wouldbe thehequivalent of the Hap tially as herein set forth.
